Question

Which is an equation in point-slope form for the given point and slope?

Point: (–2, 4); Slope: 5

A.
y + 4 = 5x – 10

B.
y + 4 = 5(x + 2)

C.
y – 4 = 5(x – 2)

D.
y – 4 = 5(x + 2)

Answer 1

These kind of problems are too hard for me

Answer 2

So, on the left with the y's there must be a 4.
on the right, there must be a -2.
And... M is obviously 5, so...

Answer 3

also for me

Answer 4

It's D.

Answer 5

well i thought it was C.

Answer 6

Which equation is graphed here?

A.
y – 2 = -3/2 (x + 4)

B.

y – 4 = - 3/2(x + 2)

C.
y+4= -3/2 (x-2)

D.y – 4 = -2/3 (x + 2)

Answer 7

Can you help me with that last question ^

Answer 8

Nope. The equation is:
The minus and the subtraction sign on the right cancel out to make it PLUS 2.

Answer 9

Yep, you bet! :)

Answer 10

So we can see that the slope is: down 3, over 2 = -3/2
So...

m = (-3/2)
And let's use (0, -1).

To find equation:

y = mx + b
(-1) = (-3/2)(0) + b
-1 = (0) + b
-1 = b
Now...

y = mx + b <-- general form
y = (-3/2)x - 1 <-- your equation

Answer 11

Or A. Sorry. Did it in the wrong form. Here:

y - y = m(x - x)
So, using (2, -4)
y - 2 = (-3/2)x - (-4)
y - 2 = -3/2(x + 4)

Answer 12

yes thats what I was gonna pick

Answer 13

Yay! :)
